Secure mechanical power transmission assemblies with our rugged forged shafts, featuring micrometric journal concentricity and precise spline profile accuracy.
CNC cylindrical grinding mills process hardened steel alloy bars, maintaining precise bearing journal diameter tolerances and AGMA compliance to prevent critical drivetrain vibration or premature bearing failure under heavy continuous loads.
Automated spline rolling lines easily manage high-volume global vehicle programs. We complement this mass-production capacity with comprehensive metallurgy services, providing complete ultrasonic non-destructive testing and induction hardening depth reports.
Our production line manufactures high-torque steel power transmission interfaces engineered to precise geometric drivetrain dimensions.
